TrstedReviews posted a review of the Sony VAIO VGN-T2XP ultra portable laptop

Inside the T2XP, the specs are pretty impressive considering the size of the notebook. Driving things along is an Ultra Low Voltage Pentium M CPU running at 1.2GHz - no doubt the choice of a ULV chip has helped the Sony achieve very impressive battery life. There’s 512MB of memory installed, but 8MB has been dedicated to the integrated Intel 855GME graphics chipset. You could allocate up to 64MB to the graphics chipset, but it really isn’t worth it - you’re better off keeping the memory accessible by your applications.
